Definitions

  • the invention relates to a method for producing a medium-tight connection between a pipe and a connector.
  • flexible spiral tubes have a lower flow resistance than ring-shaped or corrugated tubes and thereby facilitate the heat exchange between a medium running in the tube, for example a liquid, and a medium located outside the tube.
  • a medium running in the tube for example a liquid
  • spiral pipes can usually be bent freely, so that an optimal adaptability in the laying of such pipes is made possible.
  • a connector with a simple screw connection and a seal for example made of rubber
  • a seal for example made of rubber
  • such a connector causes damage to parts such as the gasket, resulting in leakage of the medium running in the pipe.
  • seals can lead to failure and penetration of a corrosive heat transfer medium into the medium to be heated (e.g. drinking water).
  • Releasable pipe-to-connector connections may also be provided, but these prior art connections are prone to leakage and failure under vibration.
  • the play or the distance between the first contour and the second contour corresponds, for example, to at least 1.1 times the wall thickness of the tube.
  • the first and second helical contour is to be understood as a thread, so to speak, which corresponds to the helically corrugated lateral surface of the pipe, which lateral surface is designed as a counter-thread to the first and second contour.
  • step e By pressing in step e), the connection between the pipe and the connector is already media-tight.
  • the term "play" is to be understood, for example, as cavities between the first contour and the lateral surface, and between the second contour and the lateral surface, this being known to the person skilled in the art. Such a game or such cavities are necessarily present in order to allow easy screwing and unscrewing of the cap ring and the screw-in socket by hand.
  • the flexible metallic tube can be a so-called spiral tube. It should be noted that there is a difference between a spiral tube and a corrugated tube in that the corrugated tube has bulges which are arranged parallel to one another and are orthogonal in the longitudinal direction of the corrugated tube, which in general do not form a thread or the like, which allows a counterpart to be screwed on.
  • the screw-in socket has a connecting section, which protrudes from the end region of the pipe when the screw-in socket is screwed into the pipe and is provided for connecting a further device for supplying and removing a medium, and a screw section, which has the second has helical contour includes.
  • connection section can have an additional thread or flange, for example, which corresponds to a connection of the further device.
  • the screw-in socket is welded to the cap ring and/or in a further step g) the cap ring is soldered to the pipe at one end of the cap ring.
  • the advantage is that the usually thin-walled pipe is protected by the union ring and the screw-in socket, so that no damage can occur to the pipe during welding.
  • the screw-in socket can be welded to the cap ring and the tube, preferably in the transition section of the screw-in socket.
  • the coupling ring has at least one chamfer on one of its ends, preferably has two chamfers on opposite ends.
  • a chamfer is generally a beveled surface on a workpiece edge.
  • the bevel angle is measured from the plane of the edge on which the bevel is placed. It can be provided that the bevel angle is designed depending on the medium used in each case. Chamfers are often applied to components to remove burrs, reduce the risk of injury and simplify further assembly.
  • the at least one chamfer of the cap ring is, for example, because of the other Solderability and protection against pipe breakage provided.
  • a further advantage of a soldered connection between the pipe and the union ring is that all the gaps are closed by the soldering and the pressing, thus preventing the risk of crevice corrosion forming.
  • Crevice corrosion occurs on metal parts in the presence of a corrosive medium in narrow, unclosed crevices such as laps and/or non-penetrating welds.
  • the driving force is the difference in concentration between the medium in the gap and in the area outside the gap, which is caused by the diffusion of the reactants being inhibited in the gap.
  • Even stainless CrNi steels can corrode in gaps if there is no protective oxide layer. Crevice corrosion can be prevented by doing without gaps in the design or by making them large enough that the diffusion of the media is not impeded.
  • Crevice corrosion occurs, for example, when the oxide layer of the stainless steel is destroyed when using stainless steel, for example by welding or mechanical scratching, or when aggressive media are present in the absence of oxygen. For this reason, crevice corrosion often occurs in narrow gaps and small cavities.
  • step e) the compression ring and the screw-in socket are pressed by means of a pressing tool.
  • the wall thickness of the tube is 2mm.
  • the length of the second contour of the screw-in socket is longer or shorter by 7 times the wall thickness of the pipe compared to the length of the first contour of the coupling ring, depending on the medium used.
  • the screw section of the screw-in socket has, at its end opposite the connection section, a closing edge which is rounded off with a radius, preferably the radius is equal to the wall thickness of the pipe.
  • the rounded edge prevents the spiral pipe from being damaged on the inside when the screw-in socket is screwed in.
  • FIG. 10 shows a detail view of a cross section of an exemplary tube 100, the tube 100 being connected to a connector 200.
  • the flexible metallic pipe 100 is first provided with a lateral surface and wall thickness s, the lateral surface being helically corrugated, the helically corrugated lateral surface being designed as a thread with thread turns and wherein the tube 100 has an end portion 110 .

  • the connecting section 251 tapers in a transition section 253 towards the screw section 252.
  • the coupling ring 210 has two opposite ends, each with a chamfer, with a first chamfer being arranged on the outside at that end which end is opposite or closest to the transition section 253 of the screw-in socket 250 , and a second chamfer on the inside at that end of the union ring 210 is arranged, which end is opposite to the connecting section 251 of the screw-in socket 250 .

  • the bevel angle ⁇ is measured from the plane of the edge on which the bevel is arranged, the bevel angle ⁇ being, for example, in 1 is drawn. Provision can be made for the bevel angle ⁇ to be formed as a function of the medium used in each case.
  • the cap ring 210 is first screwed onto the end region 110 of the pipe 100 , with play being present between the cap ring 210 and the lateral surface of the pipe 100 to ensure a free screw connection.
  • Screw-in socket 250 is then screwed into end region 110 of pipe 100 , with clearance being provided between screw-in socket 250 and the lateral surface of pipe 100 to ensure a free screw connection, and with at least a section of end region 110 of pipe 100 between the first contour 220 of the cap ring 210 and the second contour 260 of the screw-in socket 250 is arranged.
